I Application filed December Specification of Letters Patent.

OPEN FLUID/1:13.,

or Open Flumes; and I dodeclare the ollowing to be a full, clear, andexact description of the invention, such as will enable othersskilled-in the art to which itappertains :toniakeand use the same,reference being had itoj the accompanying drawings,

and to the characters of reference marked.

thereon, which form a part of this specification.

My invention relates to improvements in troughs or open flumes adaptedfor use in carrying material of any kind. The-inventidn.is,.however,more especially adapted for 1156111 carrying water for varlous uses.

My general object is to provide a sheet metal flume composed ofsections, the flume joints being formed in such a manner as to make themperfectly tight, while, at the same time, the constructlon isexceedingly economical.

An additional object to so construct, the oint as to present as littleobstruction.

as" possible to the flow of the water, or the travel of other materialthrough the trough In my improved construction, the flume sections aredepressed to form beads, which extend below orexteriorly beyond theouter surfaces of the fume sections, thesaid beads being interiorlyconcave and arranged to fit into each other, the fiurne sections overlapping at the joints.

The interior cavity of the flume joint-is filled 'bythe use-cil aclamping rod, which, as illustrated in the drawing, is semi-circular orapproximately semi-circular in cross section. The exact shape of thisclamping rod, h6wever, will depend upon the shape of the interior cavityOf tlIBJOlIIt, which is to be filled thereby. VVhile this cavity, asillus trated in the drawing, has the shape of a segment of a circle, itis evident that it may,

if desired, be of other suitable shape, the important advantage of thisfeature being that it makes it practical to substantially remove allobstructions at the Hume joints to the free passage or flow of water orother material through the fiume or trough. The clamping rod isoriginally shaped to substantially fill the cavity of the joint, its

exposed surfacebeing'flush with theinterior surface of the fiume. Itsextremities engage 'the overlapping inner ends of the hanger plates,which extend downwardly just in of the rod to get out of place.

Havin briefly outlined my improved same indetail, reference beingmadefto the accompanyin drawing, in which 'is'illiistrated an em odimentthereof- I-nthis drawing: Figure 1 is'a cross section taken through aflume'equipped with my improved construction, t-hefiume joint tion takenon the line 2-2 of Fig. 1, the parts being shown on a larger scale. Fig.3 is a top plan view of-one side of the flume, looking down on one ofthe hanger plates, the direction of the View being indicated by thearrow in Fig. 1, the parts being shown on a larger scale than in'thelast- ;n'amed figure. Fig. 4 isaj verticalsection, taken on-the linel-a-of' Fig, 3. Fig. is

several elementsseparated from each'other. .Fig. 6 is a section, similarto Fig. 2, but illustrating a modifiedform of construction. The samereference characters indicate the same parts mall the views. Let thenumeral 5 designate side sills 0r .beams, which form the support for"the flame. To the upper edges of these "beams are securedin any suitablemanner,"asfby teriorly beyond the side sills and overlap the-upper edgesof the fl'ume, which may be designated in its entirety by the numeral 8.The flume is composed of sect-ions 9 which overlap each other to formthe fiume joints. "l0.

Referring now more particularly to Figs. 1 to 5, inclusive, of thedrawing, let the numerals 12 and 13 designate the overlap ping andinterlocking bead parts of the two flume sections 9, the said beadsbeing formed by pressing the metal outwardly beyond the outer surface ofthe flume sectlons, the two beads being formed to interlock. Each-flumesection, as illustrated inthe principal views, contains a short member14, extending beyond its bead part, one member 14 engaging the innersurface of the cooperating section, while the other member 14 engagesthe outer surface of its companion section. The cavity construct1on,Iwill proceed to describe the being shown in elevation; Fig. 2 is a see--a section similar to Fig. 2, b'ut showii-ngthe' 26,191I. s i1n.ee1,ss7.-o antennae side the upper extremities of each clamping rod, thuspreventing any possible tendency bolts6, hanger. plates 7, whichprojectile vent the said rod from getting out of place.

By virtue ofthe construction just explained, it will be seen, byreferring to the drawing, that there is an exteriorly-projecting ridgeor bead at each flume joint, while the inner surface of the joint issubstantially flush with the inner surface of the flume. On oppositesides of this exterior'ridge or head are located carrier rods 18, whichare located at the angles formed by the outer bead 12 and the body ofthe flume section. The extremities 19 of these carrier rods pass throughthe extremities 16 of the hanger plates, which extend inwardly beyondthe side sills, nuts being applied to the threaded extremities of therods above the hanger plates to secure the carrier rods in place. In theform of construction shown in Fig. 6, the parts of the fiume sectionswhich overlap to form the joints are designated 20 and 21. lhese partsare the same as the parts 12 and 13, except that the extensions 14,,shown in the principal views,are wanting in the modified form ofconstruction, and, by virtue of this omission, the inner surface of thefiume is made perfectly smooth and uninterrupted at the joints. Itbecomes necessary, however, to employ an additional member 22, Whosecenter portion is concavo-convex to harmonize with the exterior shape ofthe flume joint, the extremities 23 of this member projecting far enoughbeyond the bead of the joint on the exterior surface of the fiume toform seats or bearings for the carrier rods 18, which perform the samefunction as in the other form of construction. The clampcipal views.

From the foregoing description, the manner ofconstructing my improvedtrough or flume, as well as the use of the same, will be readilyunderstood and need not be further explained in detail.

Having thus described my invention, what I claim is l. A fiume includingside sills, hanger plates secured thereto and extending interiorlybeyond the same, flume sections having exteriorly-projecting overlappingand interlocking hollow beads, a clamping rod shaped to till theinterior cavity of the bead, the extremities of the said rod abuttingagainst the interiorly-projecting extremities of the hanger plates, andmeans applied exteriorly to the fiume on each side of the jointandconnected with the hanger plates for supporting the fiume in place, thelineof centers of said means assing through said clamping rod,substantially as described.

2. A flame including side sills, hanger plates secured to the sills andprojecting interiorly beyond the same, flume, sections having theiradjacent extremities equipped with hollow beads arranged to overlap eachother in interlocking relation, a clamping rod in the interior cavity ofthe joint, the extremities of the rod engaging the overlappingextremities of the hanger plates, carrier rods applied to the securingmember on opposite sides of the joint bead and secured at theirextremities to the hanger plates,said rods being so positioned that astraight line through their centers will pierce the clamping rodsubstantially at its median line, sub- .stantial y as described.

In testimony whereof I aflix my signature in presence of two witnesses.
